Question

Which is the correct increasing order of boiling points of the following compounds.

1-Iodobutane, 1-Bromobutane, 1-Chlorobutane, Butane

• A. Butane<1-Chlorobutane < 1-Bromobuatane <1-Iodobutane
• B. 1-Iodobutane < 1-Bromobuatane < 1-Chlorobuatne < Butane
• C. Butane < 1-Idobutane < 1-Bromobutane< 1-Chlorobutane
• D. Butane < 1-Chlorobutane < 1- Idobutane < 1-Bromobuatane

Answer 1

Answer: (A)

Butane<1-Chlorobutane < 1-Bromobuatane <1-Iodobutane

Answer 2

For the same alkyl halide boiling point increases as the mass of halogen increases.
